<p>A communication system (10) has a network (12), a server (14) connected to the network (12), a computer (16) capable of accessing the server (14) via the network (12), and a portable information terminal (18) capable of performing wireless communication with the computer (16). The portable information terminal (18) and the server (14) are capable of communicating with each other via the computer (16). When the portable information terminal (18) and the server (14) communicate with each other to download a desired program and data from the server (14) into the portable information terminal (18), for example, a main memory (20) of the computer (16) is used as a data buffer. <IMAGE></p> |
